PMTCT of somatogenic genesis occurs in children with chronic somatic diseases of the heart, aorta and large vessels, lungs, kidneys, endocrine system, blood diseases and etc. Nervous system disorders in somatic diseases have much in common. Most often, at first they are functional, and then they turn into organic ones, due to metabolic disorders. And this, in turn, leads to a violation of the psychomotor development of children.
